Your liver performs more than 500 vital functions in your body. It filters toxins, supports digestion, stores nutrients, and regulates metabolism. When the liver becomes stressed or damaged, early symptoms are often mild and easy to ignore.
An LFTs test (Liver Function Test) helps detect liver problems at an early stage — before serious complications develop.
In this complete guide, you will learn:
- What an LFTs test is
- What it measures
- Normal ranges
- Symptoms of liver disease
- Who should get tested
- LFT test price
- Frequently asked questions
What is an LFTs Test?
An LFTs test is a blood test that evaluates how well your liver is functioning.
It measures specific enzymes, proteins, and waste products in the blood that indicate liver health.
Doctors recommend this test to:
- Detect liver inflammation
- Diagnose fatty liver
- Monitor hepatitis
- Evaluate medication side effects
- Check alcohol-related liver damage
- Assess bile duct problems
It is also known as:
- Liver function test
- Liver profile test
- Hepatic function panel
What Does an LFTs Test Include?
A complete LFTs test usually measures:
1. ALT (SGPT)
Indicates liver cell damage. Elevated levels suggest liver inflammation.
2. AST (SGOT)
Helps detect liver injury or muscle damage.
3. ALP (Alkaline Phosphatase)
Shows bile duct blockage or liver obstruction.
4. Bilirubin (Total & Direct)
High levels may cause jaundice and indicate liver dysfunction.
5. Albumin
A protein produced by the liver. Low levels may suggest chronic liver disease.
6. Total Protein
Measures overall protein levels in the blood.
7. GGT (Gamma GT)
Detects bile duct problems and alcohol-related liver stress.
Why is an LFTs Test Done?
Your doctor may recommend an LFTs test if you experience:
- Yellowing of skin or eyes
- Persistent fatigue
- Nausea or vomiting
- Pain in the upper right abdomen
- Dark urine
- Loss of appetite
- Swelling in legs
- Unexplained weight loss
It is also commonly advised for:
- Routine health screening
- Pre-surgery evaluation
- Chronic disease monitoring
- Long-term medication use
Normal Range of LFTs Test
Normal ranges may vary slightly depending on the laboratory, but typically:
| Test | Normal Range |
|---|---|
| ALT (SGPT) | 7–56 U/L |
| AST (SGOT) | 10–40 U/L |
| ALP | 44–147 IU/L |
| Total Bilirubin | 0.1–1.2 mg/dL |
| Albumin | 3.5–5.0 g/dL |
| GGT | 9–48 U/L |
⚠️ Interpretation should always be done by a qualified doctor.
Symptoms of Liver Problems
Liver disease can remain silent in early stages. However, warning signs may include:
- Constant tiredness
- Itchy skin
- Easy bruising
- Swelling in abdomen
- Pale stool
- Weakness
Early testing can prevent serious complications like cirrhosis or liver failure.
Who Should Get an LFTs Test?
You may need an LFTs test if you:
- Have diabetes
- Consume alcohol regularly
- Have viral hepatitis exposure
- Take long-term medications

Preventive screening helps detect problems before symptoms worsen.

The test requires a small blood sample and usually takes only a few minutes.
What Happens If LFTs Are Abnormal?

- Ultrasound liver
- Hepatitis screening
- Lifestyle changes
- Additional blood tests
Not all abnormal results mean serious disease. Early detection allows proper management.
